1)

(a)The Beraisa permits doing business with both a Nochri and a Yisrael who are going to the market (where they deal with Avodah-Zarah and other commodities). What distinction does the Tana draw between selling them something upon their return?

(b)Why is he strict regarding a Yisrael?

(c)Then why is he lenient regarding a Nochri?

(d)Why do we not say the same by a Yisrael (see Tosfos in the first Perek, 12: DH 'Aval')?

2)

(a)Why does the Beraisa permit new skin flasks of Nochrim that have not been overlaid with pitch?

(b)What if the jars are made of earthenware?

(c)What does the Beraisa say concerning old flasks or new ones that have been overlaid with pitch?

3)

(a)The Beraisa discusses a case where a Nochri overlays leather flasks with pitch and immediately pours in the wine (whilst the pitch is still hot). Why does he do that?

(b)Under which circumstances does the Tana then permit the wine?

(c)What objection do we raise to this leniency?

(d)How does Rav Papa therefore amend the Beraisa?

4)

(a)If it is the Yisrael who pours in the wine, why does one then need a second Yisrael to oversee the procedure?

(b)On what grounds does Rav Z'vid re-establish the Beraisa as it was presented? How can the Tana then permit the wine, as we asked earlier?

(c)What does Rav Papi extrapolate from Rav Z'vid's ruling with regard to a Nochri pouring wine into a vessel containing salt?

(d)On what grounds does Rav Ashi refute Rav Papi's proof?

5)

(a)Who was bar Adi?

(b)What happened to the leather flasks that bar Adi forced Rebbi Yitzchak bar Yosef to give him?

(c)When Rebbi Yitzchak bar Yosef came to the Beis-ha-Medrash to ask what to do, what did Rebbi Yirmiyah quoting Rebbi Ami rule? What would he have to do, to be permitted to use the flasks?

(d)What did Rava add to Rebbi Yirmiyah's ruling?

6)

(a)Commenting on the previous case, what did Ravin, who arrived from Eretz Yisrael rule in the name of Resh Lakish, in a case where the flask belonged to the Nochri to begin with (in which case it would have absorbed far more wine)?

(b)Rav Acha b'rei de'Rava thought that perhaps the lenient ruling is restricted to skin flasks, but does not apply to earthenware casks. Why is that?

(c)What did Rav Ashi tell him?

7)

(a)The basic Halachah of 'Shtelling' earthenware wine casks of Nochrim in water is taught in a Beraisa. Under which circumstances does the Tana dispense with the need of Shtelling, permitting earthenware jars to be used immediately?

(b)In answer to our query as to whether this leniency applies even Lechatchilah, or only Bedi'eved (permitting the fish juice ... that he already poured into the cask), Rav Z'vid bar Oshaya answers with a Beraisa. What does the Beraisa say?

33b----------------------------------------33b

8)

(a)What did Rebbi Ami reply when Rebbi Yehudah Nesi'ah asked him whether returning the wine-jars to the furnace would suffice to permit them?

(b)According to one version, Rebbi Ami concurs with this ruling. According to a second version, whom does Rebbi Asi quote who concurs with it?

(c)In fact, he permits the jars as soon as the pitch falls off from the heat. What does Rav Ashi say about this?

(d)We ask what the Din will be if one heats the jars by placing boiling hot rods inside them, until the pitch falls off. Why might this not be as good as returning them to the furnace?

9)

(a)Rav Acha and Ravina argue over the previous She'eilah. What is the Halachah?

(b)What do we learn from here regarding Kashering barrels or jars that were used for storing wine by pouring boiling water inside them?

(c)Rav Nachman and Rav Yehudah forbid using the barrels even for beer, unless they have been Kashered. Nevertheless, Ravina permitted Rav Chiya b'rei de'Rav Yitzchak to use them for beer, like the opinion of Rava. What did the latter subsequently do?

(d)Why did Ravina not then decree against using the jars for beer?

10)

(a)Rav Yitzchak bar Bisna filled jars made of earthenware and animal dung that had been used with Yayin Nesech, and placed them in the sun. Why did he do that?

(b)What happened to the jars?

(c)What did Rebbi Aba comment?

(d)Rebbi Yossi bar Avin translated 'K'lei Neser' as receptacles made of alum. What did Rebbi Yusna say about them?

11)

(a)The men of Parzak Rufila took casks by force from Pumbedisa, used them once for wine and later returned them. What does 'Parzak Rufila' mean?

(b)What did Rav Yehudah rule there with regard o Kashering the casks?

(c)And what did Rav Avira rule with regard to those barrels of red clay that one obtained from Nochrim, (even assuming that they were used for storage)?

(d)Rav Papi issued the identical ruling regarding 'Pasvasa de'bei Michsi'. What are 'Pasvasa de'bei Michsi'?

(e)What is the common reason for the two previous rulings?

12)

(a)Rav Asi requires earthenware cups to be Kashered, Rav Ashi does not. They argue in a case where a Yisrael drank the first time, and it is from the second time and onwards that the Nochri drank from it, but if he were to drink from it the first time, then even Rav Ashi would concede that it requires Kashering. Why is that?

(b)The second Lashon, which is Halachah, takes a more stringent line. What does the second Lashon say?

(c)Rav Z'vid permits a black or white earthenware vessel covered with lead (see also Tosfos DH 'Kunya') without needing to Kasher it. On what grounds is he more stringent regarding a green one?

(d)In which case will he require even a black or white earthenware vessel which is covered with lead, to be Kashered?

13)

(a)Mereimar is more lenient than Rav Z'vid. What does he say about green lead-covered earthenware vessels?

(b)What did they ask Mereimar about having to Kasher these same vessels with regard to Pesach? To which kind of vessels, even smooth ones, does the She'eilah not pertain?

(c)What did Mereimar reply?

(d)How will Mereimar now reconcile his stringent ruling by Chametz with his lenient ruling by Yayin Nesech?

(e)Why did he not answer that, whereas Chametz on Pesach is d'Oraysa, S'tam Yeinam is only de'Rabbanan?
